1 Introduction to the Window Tool Kit
initialize-windows starts up the Window Tool Kit. It allows you to use Lisp in the window provided by the existing window system, and it also gives you access to the Window Tool Kit. A new window is provided as a root viewport; any windows or viewports that you create appear in this window. A second, smaller window appears at the bottom of the window that contains the root viewport; this smaller window contains the who window.
To bring up a default initialized windows display, call the function
initialize-windows with no arguments:
(initialize-windows)If you use the host window system to close the Lisp window that contains the root viewport, the Lisp window disappears and is replaced with an icon. You can modify the image, location, label, and font of this icon; see Chapter 8, "Reference Pages" for a full description of the
Note: If the Window Tool Kit has been initialized and the function
disksave is invoked, the window environment is temporarily suspended. Once
disksave has saved the Lisp image on disk, the windows on the running Lisp image are automatically restored. See Section 1.3 on page 9 for more information.
leave-window-system exits the Window Tool Kit in such a way that you cannot return without reinitializing it.
